After bitbanging a quick library, and some head scratching, i seemed to have solved all my problems for now...

UECIDE: The Universal Embedded Computing IDE



If you haven't had the chance to check the UECIDE (The Universal Embedded Computing IDE), you should give it a thought. Arduino, AVR, chipKIT, Pinguino and many more are compatible out of the box,
chipKIT boards seem to have fully deprecated the plib.h in the included compiler tools, so beware if you are using it !

Dub Siren For The Keyboard PLayer ( Code )

For the last post DUB SIREN FOR THE LIVE KEYBOARD PLAYER, all you need is an Arduino Midi Shield (  ( you should find a local distributor for all these) , an Arduino Uno, R3 preferably, and MIDI library ( I am using the Arduino_MIDI_Library_v4.2) along with this code. NO SOLDERING DONE !

#include <MIDI.h>
//
MIDI_CREATE_DEFAULT_INSTANCE();
#define PBMAX 8191
// defines for MIDI Shield components only
#define POT  0
#define POT2  1

#define BUTTON1  2
#define BUTTON2  3
#define BUTTON3  4

#define LED  7
#define LED2  6
//
#define SINSAMPLES 256
int sineData [SINSAMPLES];
bool ledOn = false;
bool ledOn2 = false;
unsigned int inc = 0;
uint16_t noteIn = 0;
uint16_t lastnote = 0;
char off = 0;
char lastplay = 0;

//char drv = 0; // digital read variable

void setup()
{
  sine();
  pinMode(LED, OUTPUT);
  pinMode(LED2, OUTPUT);
  pinMode(POT, INPUT);
  pinMode(POT2, INPUT);
  pinMode(BUTTON1, INPUT);
  // defines for MIDI Shield components only
  digitalWrite(LED2, HIGH);
  digitalWrite(LED, HIGH);
  digitalWrite(BUTTON1, HIGH);
  //
  MIDI.begin();          // Launch MIDI
}
void loop()
{ uint16_t average = noteIn;

  uint16_t anIn = analogRead(POT);
  char play = !(digitalRead(BUTTON1));
  if (lastplay != play) {
    if (play == 0)
      off = 1;
  }
  lastplay = play;
  noteIn = analogRead(POT2);

  average = (average + noteIn) >> 1;
  uint8_t note = average >> 3;

  if (play == 1) {
    if (lastnote != note) {
      MIDI.sendPitchBend(0, 1);//reset pitch bend
      delay(10);
      MIDI.sendNoteOff(lastnote, 0, 1); // Stop the note
      delay(10);
      MIDI.sendNoteOn(note, 127, 1); // Send a Note (pitch , velo 127 on channel 1)
      lastnote = note;
    }
    else {
      lastnote = note;
    }
    int smpl = sineData[inc];
    int var = (smpl - PBMAX); // this calculation can be avoided
    MIDI.sendPitchBend(var, 1);
    delay(10);
    ledOn = !ledOn;
    digitalWrite(LED, ledOn);

    inc++;
    inc += (anIn >> 4);

      digitalWrite(LED2, ledOn2);
    }
